1. Endocrine System

Most endocrine gland functions are controlled by a negative feedback mechanism that acts to turn off hormone release as a means of controlling hormone effects. For example, after a meal, when blood glucose levels go up, the pancreas releases insulin to bind to glucose to deliver it to vital body tissues. As cells of the pancreas sense a decrease in blood glucose, release of insulin is shut off.
